Understanding virulence and manipulative strategies of gall formers will reveal new facets of plant defense and insect counter defense. Among the gall midges, the Asian rice gall midge (AGM) has emerged as a model for studies on plant-insect interactions. Data from several genomics, transcriptomics and metabolomics studies have revealed diverse strategies adopted by AGM to successfully invade the host while overcoming its defense. Adaptive skills of AGM transcend from its genomic and transcriptomic make-up. Information arising from studies on genetics, mitochondrial genome and miRNAs, amongst other parameters, highlights AGM's capacity to maneuver the host defense, reorient host metabolome and redirect its morphogenesis.
